To solve the problems exsisting in the signal acquisition and storage system, which can not simultaneously satisfy the high sampling rate and large storage capacity with no computer, this paper introduced a data acquistion and storage system based on SATA hard disc and FPGA. The system was implemented by the hardware structure included AD9627, Cyclone FPGA, PATA to SATA chip JM20330; the software was programmed by Verilog HDL, Altera＇s FPGA was used to achieve data channel selection and control the disc-array, processing the large capacity high-rate data acqusited by the A/D chip, then recorded the data to the SATA hard disc through the pata-to-sata chip. Result indicates that this system can acquiste the data in a sampling rate up to 150M,and achieve the large capacity storage without computer. Compare to the acquisiton and storage systems before, the data acquistion and storage technology based on SATA and FPGA shorten the development period of the specific SATA controller; relieve the pressure inside the system; improve the storage speed, safety and interference immunity; finally implement the large storage capacity system.
